Question 1152886
.
<pre>

The space of events is this set with the associated probabilities


    HH   0.7*0.7 = 0.49

    HT   0.7*0.3 = 0.21

    TH   0.3*0.7 = 0.21

    TT   0.3*0.3 = 0.09.


The probability that both tosses have the same output is


    P = P(HH) + P(TT) = 0.49 + 0.09 = 0.58.    <U>ANSWER</U>
